Additional special features for other half-integer Γ’s suggest new surprises in the supergravity models. These features are manifest in this definition because the relevant solutions of the string equation have special properties for Γ = ± 1 2.

In fact, Γ = ± 1 2 yields the cases (0,2) and (2,2) that were shown by Stanford and Witten to have very special properties. This cookie is set by GDPR Cookie Consent plugin. Business Address: Strings and Beyond 109 N. Here, half-integer Γ also has an interpretation. Excited by our discoveries it made sense to help other cellists benefit from the sound our strings can create, and so Rostanvo was born. A central role is played by a nonlinear “string equation” that naturally incorporates Γ, usually taken to be an integer, counting, e.g., D-branes in the minimal models. The minimal models come from double-scaled complex matrix models and correspond to the cases ( 2 Γ + 1, 2 ) in the Altland-Zirnbauer ( α, β ) classification of random matrix ensembles, where Γ is a parameter. This construction defines nonperturbative physics for the supergravity that is well defined and stable. It is proposed that a family of Jackiw-Teitelboim supergravites, recently discussed in connection with matrix models by Stanford and Witten, can be given a complete definition, to all orders in the topological expansion and beyond, in terms of a specific combination of minimal string theories. Rotosound has produced instrument strings and accessories for more than 60 years from its family-run factory in Kent, England.
